Định Nghĩa và Ý Nghĩa của "a friend to all is a friend to none"

What is the origin of the proverb "a friend to all is a friend to none" and when to use it?

The proverb "a friend to all is a friend to none" originates from the ancient Greek philosopher Aristotle. It suggests that attempting to be friends with everyone results in superficial relationships that lack the depth and loyalty true friendships require. Genuine friendship demands commitment and intimacy that cannot be extended to a large number of people. Thus, those who try to please everyone often end up with no meaningful connections. This proverb serves as a reminder to prioritize and nurture a few deep, meaningful friendships rather than spreading oneself too thin.
